The Yellowish color doesn't match at all! It's too bright for the other colors which are more dull. Maybe a darker mustard would be better if you wanted to still use that yellowish scheme.
For your WOL, The brown supermoderator color doesn't match. Too dark. And why are the Active Users Today WOL colors different? That may be confusing for others. Also with your categories not seperated I don't think you need the Forum, Mod etc. title under each category name.
Also your banner is a little too long, maybe it shorter or make it long like here and put the nav stuff underneath it.
For your thread list, I like it better with the announcement in a new table, thats what made it good.
Your postbit is nice, although the author table can get a little confusing at times.
But nice work.
